Patents by Inventor Cheryl D. Hartfield

Cheryl D. Hartfield has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8759765
    Abstract: A method for processing a sample in a charged-particle beam microscope. A sample is collected from a substrate and the sample is attached to the tip of a nanomanipulator. The sample is optionally oriented to optimize further processing. The nanomanipulator tip is brought into contact with a stabilizing support to minimize drift or vibration of the sample. The attached sample is then stabilized and available for preparation and analysis.
    Type: Grant

  • Patent number: 6752012
    Abstract: An apparatus (30) and method (80) for predicting electrical property stability of a thin film or conductive substrate (14) prior to multi-probe testing. The present invention utilizes a nanoindenter type device (10) obtaining mechanical properties as a function of displacement depth and applied load into the bond pad surface to accurately predict electrical property stability of the entire substrate or sample under test. In addition, the present invention includes a nanoindenter type device (10) including a second probe (34) having the ability to measure localized electrical properties of the sample while obtaining the mechanical property measurements. This additional electrical measurement is correlated with the mechanical property measurements to accurately predict electrical property stability of the entire conductive substrate, preferably by predicting the presence of an unwanted material surface layer.
